数据字典不一致造成大量ORA-600和ORA-7445错误

原创 Linux操作系统 作者:yangtingkun 时间:2012-03-23 23:37:11 0 删除 编辑

测试环境中,由于将数据字典表错误的导入到当前的数据库SYS用户下,导致数据字典出现了不一致的状态,反应出来的结果就是大量的ORA-600ORA-7445错误。

 

 

列几个错误信息,简单记录一下这个问题:

这些错误中,有个别错误在MOS中就没有任何记录,而另外一些,虽然存在记录,但是都和当前的错误现象不符。且所有的错误都是在数据字典不一致后出现的,因此可以确定,这些错误都与数据字典不一致有关。

一般情况下,数据库不会产生这种异常,如果真是由于导入或者直接修改导致数据字典的异常,那么推荐采用exp导出,重建imp导入的方式来解决问题。

最后还要强调一次,数据字典的修改是非常危险的,无论是有意为之还是无心之过。
